WELL-MACHINE.

Specification of Letters Patent.

Patented Dec. 25, 1906.

Application filed nu ryll, 1905. Serial No. 240,635.

To all whom it may concern:

Be it known that I, MICHAEL LEININGER, acitizen of the United States of'America, and a resident of Chicago, Cook county, Illinois, have invented a certain new and useful Improvement in Well-Machines, of which the following is a specification.

My invention relates to Well-making machinery of that particular character in which the drill or tool for drilling is attached to the lower end of the rope or cable and in which means are provided for alternately drawing the tool up a proper distance and then allowing it to fall, so as to produce a vertical reciprocation, so to speak, of the said tool and in which also there are suitable means for paying out the rope or cable as fast as the work progresses and the depth of the well increases.

Generally stated, the object of my invention is to provide an improved, simplified, and highly-efficient well-machine of the fore going general character.

A special object is to provide'an improved arrangement for operating the rope or cable that is to say, for reciprocating the tool which is employed in drilling the well.

Another object is to provide an improved arrangement for paying out the rope or cable, and thus gradually lowering the tool as the work progresses and the depth of the well increases.

A further object is to provide improved means for varying the length of the stroke of the tool.

An additional object is to provide an improved construction and arrangement for hoisting or drawing up the tool from the loottom of the well. I

It is also an object, of course, to provide certain details and features of improvement tending to increase the general efficiency and serviceability of a well-machine of this particular character.

To the foregoing and other useful ends my invention consists in matters hereinafter set forth and claimed.

The single figure of the accompanying drawing is a perspective of a well-machine embodying the principles of my invention.

As thus illustrated, oWer is communicated to the drive-shaft by means of a pulley B. The pinion C, which is mounted on a spline or feather upon the shaft A, engages the gear-wheel D. This gear-wheel is in turn mounted upon a crank-shaft E, provided with a crank-arm F, the latter serving as a tri per. The rope or cable 1 for drilling the wel is operated by a tripper-block G, secured to the free or up-and-down swinging end portion of the arm H, the latter being mounted upon a horizontally-disposed shaft I. An arm J, provided with a sheave K, adapted to bear down upon the said rope or .cable, is secured to the forward end of the arm H. As shown, the roller or knob L slips off from the said tripper-block G, and the rope or cable is thereby released and the tool allowed to fall and strike the desired blow.

The length of stroke of the tool can be varied by moving the roller or knob L toward or away from the end of the crank-arm F, and the same effect can be obtained by varyingthe length of the chain 2 by means of a pin M, so as to limit the upstroke of the arm H. It will be seen that this chain connects the said arm H with the frame of the machine. upon a drum N, adapted to rotate upon a vertical axis. A horizontally-disposed shaft O is provided with a pinion I, adapted to engage a gearwheel Q, carried by the said drum. Said shaft 0 is also provided with a band-brake device R, arranged to be operated by a hand-lever S. By releasing this brake the rope or cable can be paid out at the desired rate of speed. As illustrated, the rope or cable can be wound up and the tool hoisted out of the well by means of a crank T, secured to the shaft 0, or, if desired, the pinion C can be disengaged from the gear D by means of a shifter device U. After this the sprocket-wheel V can be made to rotate with the shaft A by closing the clutch W by means of the hand-lever. The sprocket-wheel V is, it will be seen, connected by a sprocketchain with the sprocket Y on the shaft 0. In this way the power can be disconnected from the tripper and then connection made with the shaft 0, so that the power can be employed for winding in the rope or cable and hoisting the tool out of the well. From the foregoing it will be seen that I provide a simple and h'ghly-improved construction of well -machines, comprising comparatively simple and effective devices for operating and controlling the drill or tool.

What I claim as my invention is* 1. A well-machine comprising a rope or cable for reciprocating the tool, means for operating said rope or cable, a drum mounted to rotate upon a vertical axis and having The said rope or cable 1 is woundan end portion of said rope or cable wound I regulated through the medium of the shaft thereon, a horizontally-disposed shaft, pro- A and pinions O. vided with gear connection with the base of 5. Inawelhmachine, the combinationWith said drum, a band-brake applied to and l the drum N,acable wound thereon, apivotal adapted for controlling the rotation of said arm H carrying an upwardly-extending arm shaft, and a hand-lever suitably connected J on which is mounted a sheave K adapted to for operating said handbrake, whereby said l bear upon said cable, a crank-shaft E prorope or cable may be paid out at will and as vided with a gear-wheel D and a crank-arm fast as the depth of the well increases.

with a rotary drum, of a cable wound upon said drum, a pivotally-attached arm, a a brake-lever S, a shaft A and pinions C, the

sheave attached thereto adapted to bear upon said cable, a drive-shaft provided with a pinion, a gear-wheel engaging therewith, a tripper-arm, a roller adjustably mounted thereon, a tripper-block mounted on said pivotally-attached arm, and means for limiting the movement of said arm.

3. In a well machine, the combination With the drum N, a cable wound thereon, a pivotal arm H carrying a sheave K adapted to bear upon said cable, a crank-shaft E provided with a gear-wheel D and a crank-arm F and a tripper-block G, said cra11k-arm being adapted to engage and release the arm H through the medium of the tripper-block G.

4. In a well machine, the combination With the drum N, a cable wound thereon, a pivotal arm H carrying a sheave K adapted to bear upon said cable, a crank-shaft E provided with a gear-wheel D and a crank-arm F and a tripper-block G, said crank-arm being adapted to engage and release the arm H through the medium of the tripper-block G, the movement of said drumN being regulated through the medium of a brake-lever S, and the movement of the crank-arm F being through the medium of the brake-lever S, and the movement of the crank-arm F being regulated through the medium of the shaft A and pinions C.

6. In a well-machine, the combination ofa frame, a drum N, a vertical cable attached thereto, a horizontal rotary shaft A, a horizontal crank-shaft E, gearing C and D forming a connection between said shafts, a horizontal shaft 0, brake means provided therefor, and a pinion adapted to engage the gear on the drum N, an arm H carrying a sheave ,K and cable held in place by said sheave, dropping mechanism, the movement of said drum being regulated b T the braking means secured to the shaft 0, and the dropping mechanism being regulated by the movement of the shaft A.
